      Dude your running squid.. So all your queries are done by the proxy.. And proxy would use what?? Prob what is in general setup of psfense.

      This is broken!!
      209.200.164.69 expired, rto 48821432 msec, tA 0 tAAAA 0 tother 0.
      209.200.165.74 expired, rto 48821432 msec, tA 0 tAAAA 0 tother 0.

      Flush your infra cache, then do some queries direct to pfsense... Then look in your infra_cache you can flush with.
      flush_infra all

      Do quite a few queries for different things..

      You just flushed the cache, so it can answer stuff from its cache... So you need to ask for stuff that is not in the cache

        Why would squid be doing the lookups? It's not listening on 53. And I'm not going through the proxy personally (explicit mode, not transparent) so squid is out of the loop.

          Why would you be running a proxy if not using it? Makes ZERO sense to run a proxy if not having clients use it.

          When browser asks proxy for www.whatever.com - proxy is what looks up www.whatever.com no the client wanting to go to www.whatever.com

          Your current infra has bunch of shit blocked with those expired and RTO... Dump its cache, then do some queries direct to pfsense and then look at the infra cache..

          We are trying to get some info that unbound is actually working!

          You sure you didn't put in a dns redirect and sending your dns queries to pfsense to your AD?

            You're getting off-track here. I run a proxy for my non-admin users. I''m the admin. No proxy for me.

              You have shown no info at all that unbound is even working... When you show proxy running... Then I assumed that is what the VAST majority of stuff would be using to get to the net and could explain not seeing large infra cache, etc.

              Do my test.. with the dump and explicit queries to pfsense running unbound so we can get some valid info in your infra cache... But RTO of bajillion tells me your not talking to anything..

                    We just show what unbound dumps out. If it's empty, then it's empty in unbound. That could be for any number of reasons, all up to unbound. If you have something like pfBlockerNG and DNSBL active that could contribute to any differences you see. Also keep in mind if you have DHCP registration active for the DNS resolver, unbound will restart for each lease change that triggers a hostname update.

                        Well that output looks normal... That is your infra cache for that domain, in what would be used to look it up... So you should see the full cache output in the gui then.

                        As jimp stated all that gui is showing you is the output of the command dump_infra

                          Yes, I get that. What I don't get is how this list is empty, then 5 minute later it's full, then 5 minutes later it's empty. Does it really flush that frequently?

                            When you talk to the roots in resolver mode there isn't much reason to keep around data for dozens of authoritative servers you may not talk to again for who knows how long.

                            If you have the DNS Resolver in forwarding mode, it will show your forwarders there for much longer.

                            But again, unbound could be clearing that for any other reason, like a restart

                              The infra cache entries should stay their for the length of the ttl..

                              Yeah if your unbound is restarting then the cache is going to be dumped.

                              If you have it registering dhcp leases and you have lots of clients getting leases all the time then yeah it could be restarting every few minutes. Which makes the cache pretty useless to be honest ;)

                                I've already checked that Unbound is not restarting frequently. In fact, it hasn't restarted since its last boot 49 days ago in late January.

                                  Well something is dumping the infra cache then.. You have any crons setup? Do you have pfblocker installed?

                                  If unbound is up and running and being asked there would always be plenty of info in that cache.. Hmmm did you mess with the number of entries int he advanced tab?

                                  Did you change the
                                  TTL for Host Cache Entries
                                  Setting from its default 15 min to say 1 min or something?

                                    @kom said in DNS Resolver Status, no data?:

                                    I've already checked that Unbound is not restarting frequently. In fact, it hasn't restarted since its last boot 49 days ago in late January.

                                    Sometimes (after reboot or WAN toggle) Unbound doesn't log anything to Status / System Logs / System / DNS Resolver.

                                    Restarting Unbound from Status / Services tab will get it to log.

                                      Right, I odn't have time to chase this anymore. I put Resolver into forwarding mode and that's that.

                                        You weren't doing dnssec anyway so doesn't matter. Can not 2 secons to look to see if you this setup you got from 4 years ago didn't adjust the infra ttl to 1 minute..

                                          TTL for Host Cache Entries was set to 15 minutes. I definitely haven't touched that one. Wasn't even aware of it. It's entirely possible, and likely, that I was underestimating the time before the flush.

                                            That is not a flush, that is the max time a TTL can be set before it will timeout, etc. That is not a dump of the cache.

                                            Let me state this again... If your resolve was working the info in the infra cache is beyond noise to someone that doesn't understand what any of it means.

                                            You have no need to look down that rabbit hole if your not trying to troubleshoot a specific issue... Was resolver working? How many queries does it get in normally, if yours has been up for 49 days and your total number of queries was

                                            total.num.queries=7233

                                            Nobody is even asking pfsense anything...

                                            Here I restarted unbound what yesterday and have
                                            total.num.queries=19015
                                            total.num.queries_ip_ratelimited=0
                                            total.num.cachehits=16215
                                            total.num.cachemiss=2800

                                            And I only have a couple of boxes on my home network... As I brought up before you have pretty much everything using your proxy and or AD dns.. So what your doing on pfsense prob has zero to do with anything. You should prob turn it off and see who complains, since your having pfsense ask your AD for its own dns anyway. And from the entries you did have in your cache couldn't even talk to outside dns.

                                            BTW: I have been doing dns for years and years, for some very large networks.. And also its just hobby of mine I love the way it works and how it does what it does so fast and efficient.. And I can tell you have never had need to look into such info.. Can not recall when I ever dumped the infra cache other to see if there there were huge amounts of timeouts and such.. Even if you manage dns for a huge network, you most likely would never have need to view that info like that... You might use the lookup command we did to see what your resolver is using.. But raw full dump of the infra - no its eye candy in the menu to impress new users that don't really understand dns anyway ;) My take on why they put it in..

                                            If they wanted to put up some useful/interesting eyecandy they would do like the total number of queries, percent cache hit,

                                            This info would be more interesting that the raw infra_dump

                                            num.query.type.A=7801
                                            num.query.type.SOA=15
                                            num.query.type.PTR=9895
                                            num.query.type.TXT=21
                                            num.query.type.AAAA=1388
                                            num.query.type.SRV=246
                                            num.query.class.IN=19366

                                            num.answer.rcode.NXDOMAIN=10067

                                            That NXdomain means something is asking quite a bit actual for something that doesn't exist and gets returned NX.. So should prob look into that..

                                            edit: Ok found it ;)

                                            Mar 14 13:40:56 	unbound 	5708:1 	info: 10.0.8.3 HNA00050.snipped.internal.com. A IN NXDOMAIN 0.000000 1 121 
                                            

                                            Had unbound log queries and replies.. My shitty ass work laptop connected to my vpn to home is bombing nonsense down to my pfsense dns ;)

                                            Just noise.. But should prob spend some time making sure my work laptop doesn't do that...

                                            edit: Ok that corrected, simple acl to deny nonlocal from my laptops vpn IP... That way doesn't keep telling my Laptop NX for stuff it should be able to lookup from the local dns..
